Patent number: 11859129Abstract: A method of forming a permeable proppant pack in a geothermal formation can include injecting a fracturing fluid into a fracture of a geothermal formation having a formation temperature greater than about 275° C. The fracturing fluid can include proppants having a core of a solid material that is thermally stable at the formation temperature. The core can be at least partially coated with a resin coating that includes a polymer having a decomposition temperature below the formation temperature and a melting temperature below the decomposition temperature. The resin coating can be decomposed by the heat from the geothermal formation and the core of the proppants can remain in the fracture after the resin coating has decomposed.Type: GrantFiled: December 7, 2022Date of Patent: January 2, 2024Assignee: ALTAROCK ENERGY INC.Inventors: Matt Uddenburg, Geoff Garrison, Susan Petty

Patent number: 11661857Abstract: The present disclosure describes methods and systems for generating electricity. A method of generating electricity can include evaporating water with a low grade heat source to form low-temperature steam. The low-temperature steam can be superheated to a superheated temperature by transferring heat to the low-temperature steam from a thermal energy storage that is at a temperature higher than the superheated temperature. A steam turbine generator can be powered with the superheated steam to generate electricity. The thermal energy storage can be recharged using electricity from an intermittent electricity source.Type: GrantFiled: June 16, 2021Date of Patent: May 30, 2023Assignee: Cyrq Energy, Inc.Inventors: Matt Rosenfeld, Susan Petty

Patent number: 9458694Abstract: A system and method for extending a slotted liner shoe is disclosed. According to one embodiment, a low density material is injected into a liner having a plurality of openings. The liner is suspended below a cemented casing in a wellbore of a well in a subterranean formation.

Patent number: 9090810Abstract: A method can include introducing a particulate diverting agent into a first fracture within an underground reservoir formation. The particulate diverting agent can at least partially hydraulically isolate the first fracture. The particulate diverting agent can also be a temporary material which substantially degrades over an extended time. The underground reservoir formation can be stimulated with a stimulation fluid sufficient to expand a second fracture within the underground reservoir formation. The particulate diverting agent can then be allowed to substantially degrade.Type: GrantFiled: December 14, 2011Date of Patent: July 28, 2015Assignee: AltaRock Energy, Inc.Inventors: Daniel L.
